VSC, A-TRAC, DAC functions disabled, solution

[Jakeepoo3]

Symptoms- VSC light on with check engine
light. No abs light.
-all ABS related functions disabled
-weird rpm fluctuations under no
throttle or braking.
-annoying

Solution-manually pulled codes via DLC.
Seven codes pulled (picture attached)
-focused on code which is an input for
all my other trouble codes (C1413)
Front right speed sensor malfunction.
-test harness and sensor for correct
resistance and voltage values.
-CLEAN SPEED SENSOR MAGNETO
TONE RING with q-tips and pipe
cleaner.
-blow out with compressed air

My whole truck works again skee pee!! Check this picture out. All these codes thrown from a dirty tone ring! Thought this might help some people out there that know their gas cap is on right seems to be a common issue on here with no good answers.

That's awesome, great troubleshooting! For future search reasons (maybe me one day!) I've transcribed some of your hand written notes below:

-C1443 Data not received for yaw sensor
-C1413 Front right speed sensor, check sensor, speed rotor, and harness
-C1427 ABS control unit shutdown...
-C1429 Brake pedal switch, monitored by skid ECU
-C1251 Open in ABS pump motor, no signal from skid control ECU
-C1963 Stability control inhibit steering angle sensor no input
-C1156 Wheel speed sensor communication, no steering angle input

And in this case C1413 seemed to be the main culprit fixed by cleaning the speed sensor magneto tone ring with Q-tips, pipe cleaner, and compressed air.

Thanks sir! Hopefully it helps someone out one of these days

I went through the same process a few months back.

Hey partner what was your situation? Is this bad luck, that photo looks familiar?!
